I have x230 with LP125WH2 SLB3 screen and I absolutely love it, although I don't have an older generation laptop display to compare. Ghosting, blacklit, colors - it is all ok for me, but what's especialy great it is the contrast. I also love white balance. The screen is very brigh for indoor use. Do not know about outdoor, I guess no screen will be bright enough for that. The only problem I have now, and this is the reason I'm posting this message, I cannot find decent 22"-24" monitor which would be even remote match to the x230 on picture quality. Larger IPS monitors which I saw are not even close to the LP125WH2 SLB3 when it comes to comfort for eyes and I think i's because of contrast. I worked on 23EA63V-P, U2412M and VS24AH-P and they are all lame compared to x230 display, there were problems with white balance on first two (could be defective though). They also make my eyes hurt. Sadly enough, I didn't have this problem until I bought x230. Now working on VS24AH-P but thinking of returning it too. Maybe I need to look at other technology, something like PVC display?
